Description

【０００１】
【発明の属する技術分野】
本発明は、少なくとも１つの駆動ケーブルおよび駆動される従動ピニオンを含む、可動の車両部材、特に、開閉可能な車両ルーフのカバー部材のための可動車両部材用駆動装置に関する。
【０００２】
【従来の技術】
このような駆動装置は、例えば、スライドルーフのカバーなどのために汎用される。この場合、従動ピニオンは、一般に、変速伝動装置を介して電動機によって駆動され、ピッチケーブルとして構成された２つの並列の駆動ケーブルの間に設置され、それぞれ、１つの箇所に直接に係合して上記駆動ケーブルを逆方向へ駆動する歯車として構成されている（例えば、ドイツ特許公開第４３１３６８７号Ａ１参照）。
【０００３】
更に、独自の変速伝動装置を介して独自の電動機によってそれぞれ駆動され、それぞれ１つの箇所で係合して２つの駆動ケーブルを逆方向へ駆動するため上記駆動ケーブルに直接に係合するよう上記駆動ケーブルの間に２つの別個の従動ピニオンを設けた形式の、可動の車両ルーフ部材のためのタンデム駆動装置は、例えば、ドイツ特許第１９７３４８１５号に記載されている。
【０００４】
【発明が解決しようとする課題】
この従来装置の場合、双方の駆動ケーブルの各々への力の導入は、順次に配列された２つの箇所において行われるが、このために、２つの別個の駆動装置を設ける必要があり、従って、経費増を招く。
上記の公知の駆動装置には、従動ピニオンに大きいトルクを加えた際、各駆動ケーブルの力導入箇所が強く負荷され、その結果、ケーブル側またはピニオン側に破損が誘起されることになるという欠点がある。
【０００５】
本発明の課題は、駆動装置から１つまたは複数の駆動ケーブルに先行技術に比してより大きい力を導入できるようにした可動車両部材用駆動装置を創成することにある。
【０００６】
【課題を解決するための手段】
この課題は、本発明にもとづき、請求項１に開示の如き駆動装置によって解決される。この解決法の場合、従動ピニオンに与えられた駆動力は、少なくとも２つの箇所において１つまたは複数の駆動ケーブルに導入され、従って、それぞれ１つの箇所においてのみ駆動ケーブルへの力導入を行う公知の駆動装置に比して、力導入箇所の負荷が著しく減少され、即ち、一般に、少なくとも１／２になるという利点がある。
【０００７】
駆動アッセンブリ（駆動ユニット）が、１つまたは複数の駆動ケーブルにそれぞれ係合する少なくとも２つのケーブル車を含み、従動ピニオンの回転のための変速機構として構成すれば好ましく、この場合、ケーブル車を歯車として構成し、１つまたは複数の駆動ケーブルをピッチ面付ケーブルとして構成するのが合目的的である。
第１実施形態の場合、駆動アッセンブリは、従動ピニオンと直接に係合する合計２つの歯車を含み、この場合、従動ピニオンは、歯車の歯と係合し、従動ピニオンおよび歯車は、本質的に１つの平面内にある。この場合、双方の歯車の径または歯数は、僅かに異なつてよく、この場合、従動ピニオンの歯数は、変速実現のため、歯車の歯数よりも少なければ好ましい。この実施形態の場合、構造が簡単であるという利点が得られる。
【０００８】
他の実施形態の場合、駆動アッセンブリは、ケーブルと係合する歯車が伝動装置を介して従動ピニオンによって駆動されるよう構成されており、この場合、駆動アッセンブリが、ケーブルと係合する２つの歯車と、上記歯車と同軸に配置され空転しないよう結合されそれぞれ従動ピニオンと直接に係合する２の歯車を有するよう構成するのが好ましい。この実施形態の場合、各歯車の対応する構成によって、第１実施形態の場合よりも更に大きい変速が可能である。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図１−５に、可動の車両部材、好ましくは、開閉可能な車両ルーフのカバーまたは他の被覆部材、例えば、スライドルーフまたはスライドチルトルーフのカバーまたはスラットルーフのスラットのための駆動装置の第１実施形態を示した。ルーフ固定のフレーム１０には、従動ピニオン１２、２つの歯車１４；１６および２つの案内パイプ１８；２０が設けてあり、この場合、上記案内パイプは、可動カバー、その他に公知の態様で一端を固定した２つのスパイラルケーブルまたはピッチ面付ケーブル２２；２４を案内する。ルーフフレーム部材１０は、更に、軸受カバー２６（図１には示してない）を備えている。図５に示した如く、従動ピニオン１２は、公知の態様で、ウォーム伝動装置２８のウォーム歯車によって駆動される。この場合、ウォーム歯車は、駆動電動機３０のシャフトの前端に設けたウォームシャフトと噛合い、従って、従動ピニオン１２の回転は、電動機シャフトの回転に関して強く減速される。
【００１０】
歯車１４、１６およびピニオン１２の回転軸線または支持軸線は、１つの直線上に配置されている。この場合、歯車１４、１６およびピニオン１２は、双方の案内パイプ１８、２０の間に、即ち、駆動ケーブル２２、２４の間に設けてある。案内パイプ１８、２０は、開口３２を備えており、歯車１４、１６は、それぞれ、上記開口を介して駆動ケーブル２２、２４と係合し、この場合、各歯車１４、１６は、それぞれ、厳密に１つの箇所で各ケーブル２２、２４と係合する。従動ピニオン１２は、歯車１４、１６と同一の歯列面に設けてあり、双方の歯車１４、１６と噛合い、従って、１つの方向への従動ピニオン１２の回転は、歯車１４、１６の逆方向の同速の回転を誘起し、上記歯車は、同じく従動ピニオン１２から伝達されたトルクを駆動力として駆動ケーブル２２、２４に導入し、かくして、上記駆動ケーブルは逆方向へ駆動され、この場合、双方の駆動ケーブルの各々への力の導入は、２つの箇所、即ち、歯車１４の係合点および歯車１６の係合点において行われる。従動ピニオン１２の所与のトルクにおいて、かくして、駆動ケーブル２２、２４への各力導入箇所の負荷は、従動ピニオンのトルクが駆動ケーブルに直接に作用する先行技術に比して、総合して本質的に１／２に減少される。本発明の場合、従動ピニオン１２は、駆動ケーブル２２、２４と係合しない。従動ピニオン１２の径または歯数は、歯車１４、１６のそれよりも小さく、従って、従動ピニオンから駆動ケーブルへの直接の力導入に比して減速が行われる。歯車１４、１６の歯数は、若干異なっていてよく、この場合、かくして、案内パイプ１８、２０および駆動ケーブル２２、２４の位置は、正確には平行ではない。例えば、歯車１４、ピニオン１２および歯車１６について下記の歯数を選択できる：２２／１６／２５および２３／１５／２６。理論的に、同一の歯数も可能である。
【００１１】
従動ピニオン１２によって駆動される歯車１４、１６が駆動ケーブル２２、２４に直接に係合する図１−５の実施形態の本質的利点は、所要コンポーネント数および高さ方向の所要構造スペースが僅かであるという点にある。しかしながら、歯車１４、１６の歯は、ピッチ面付ケーブル２２、２４および従動ピニオン１２の歯との係合に好適でなければならないので、歯列の種類の選択は自由ではない。即ち、例えば、伸開線歯列は不可能である。
図６−８に示した実施形態は、上述の直接的係合の実施形態とは、下記の点において本質的に異なる。即ち、駆動ケーブル２２、２４と係合する双方の歯車１１５、１１７は、直接に駆動されるのではなく、即ち、同一歯列面内で従動ピニオン１２で駆動されるのではなく、このために、それぞれ従動ピニオン１２と直接に係合し、歯車（２次歯車、セカンダリギヤ）１１５、１１７を駆動するために上記歯車に関して同軸に空転しないよう設置された補足歯車（１次歯車、プライマリギヤ）１１４、１１６が設けてある。このため、それぞれ、歯車１１４、１１５および歯車１１６、１１７を空転しないよう設置した共通のシャフト１４０が設けてある。従動ピニオン１２と係合する１次歯車１１４、１１６の歯数を対応する２次歯車１１５、１１７の歯数よりも大きく選択すれば、従動ピニオン１２の回転を補足的に減速できる。この実施形態の更なる本質的利点は、駆動ケーブル２２、２４と係合する２次歯車１１５、１１７の歯列および従動ピニオン１２と係合する１次歯車１１４、１１６の歯列は、異なる態様に選択でき、即ち、当該の係合目的に関して最適化できるという点にある。この場合、特に、伸開線歯列も可能である。既述の実施形態に対するこの実施形態の欠点は、高さ方向のより大きい所要構造スペースおよび補足コンポーネント（２つの補足歯車）の使用にある。
【００１２】
総括して、本発明は、従動ピニオンの所与のトルクを駆動ケーブルに伝達するために、各ケーブルについて少なくとも２つの力導入箇所を設けることによって、ケーブル当り１つの力導入箇所のみを設けた先行技術に比して、力導入箇所の負荷が本質的に減少され、従って、一方では、駆動装置の信頼性が向上され、他方では、極めて大きい駆動力を伝達する必要があるルーフシステム（例えば、キャブリオレーの大形ルーフシステム）に使用できるという利点を与える。
以上詳述した本発明においては、少なくとも１つの駆動ケーブル２２、２４および駆動される従動ピニオン１２を含む可動車両部材用駆動装置において、次のような特徴を有する。
【００１３】
第１に、従動ピニオン１２が、１つまたは複数の駆動ケーブル２２、２４を駆動するために上記の１つまたは複数の駆動ケーブルにそれぞれ少なくとも２つの箇所で係合する駆動アッセンブリ（歯車１４、１６、１次歯車１１４、１１６、２次歯車１１５、１１７）を駆動する。
これによって、従動ピニオン１２に与えられた駆動力は、少なくとも２つの箇所において１つまたは複数の駆動ケーブルに導入され、各力導入箇所の負荷が著しく減少される。
【００１４】

BACKGROUND OF THE INVENTION
The present invention relates to a movable vehicle member drive device for a movable vehicle member, in particular a cover member for an openable and closable vehicle roof, comprising at least one drive cable and a driven follower pinion.
[0002]
[Prior art]
Such a drive device is widely used for a cover of a slide roof, for example. In this case, the driven pinion is generally driven by an electric motor via a transmission and installed between two parallel drive cables configured as pitch cables, each directly engaging one location. The gear is configured to drive the drive cable in the reverse direction (see, for example, German Patent Publication No. 4313687 A1).
[0003]
In addition, each drive is driven by its own electric motor via its own transmission gear, and each drive engages at one location and directly engages the drive cable to drive the two drive cables in opposite directions. A tandem drive device for a movable vehicle roof member in the form of two separate driven pinions between the cables is described, for example, in German Patent No. 197334815.
[0004]
[Problems to be solved by the invention]
In the case of this conventional device, the introduction of force into each of the two drive cables takes place at two points arranged in sequence, which requires the provision of two separate drive devices, and therefore Incurs increased costs.
In the above known drive device, when a large torque is applied to the driven pinion, the force introduction portion of each drive cable is strongly loaded, and as a result, damage is induced on the cable side or the pinion side. There is.
[0005]
It is an object of the present invention to create a drive device for a movable vehicle member that allows a greater force to be introduced from the drive device to one or more drive cables compared to the prior art.
[0006]
[Means for Solving the Problems]
This problem is solved according to the invention by a drive device as disclosed in claim 1. In the case of this solution, the driving force applied to the driven pinion is introduced into one or more drive cables in at least two locations and is therefore known to introduce force into the drive cable only in one location each. Compared to the drive, there is the advantage that the load at the point of force introduction is significantly reduced, i.e. generally at least ½.
[0007]
Preferably, the drive assembly (drive unit) includes at least two cable wheels that respectively engage one or a plurality of drive cables, and is configured as a speed change mechanism for rotation of the driven pinion. It is expedient to configure one or more drive cables as pitch faced cables.
For the first embodiment, the drive assembly includes a total of two gears that engage directly with the driven pinion, where the driven pinion engages the gear teeth and the driven pinion and gear are essentially Be in one plane. In this case, the diameters or the number of teeth of both gears may be slightly different. In this case, it is preferable that the number of teeth of the driven pinion is smaller than the number of teeth of the gear in order to realize a speed change. In this embodiment, the advantage that the structure is simple is obtained.
[0008]
In other embodiments, the drive assembly is configured such that the gear that engages the cable is driven by a driven pinion via a transmission, in which case the drive assembly has two gears that engage the cable. It is preferable to have two gears that are arranged coaxially with the gears and that are coupled so as not to idle and that directly engage the driven pinion. In the case of this embodiment, a larger shift is possible than in the case of the first embodiment by the corresponding configuration of each gear.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1-5 shows a first of a drive device for a movable vehicle member, preferably a cover or other covering member for an openable / closable vehicle roof, for example a slide roof or a slide tilt roof cover or a slat roof slat. Embodiments have been shown. The roof fixed frame 10 is provided with a driven pinion 12, two gears 14; 16 and two guide pipes 18; 20. In this case, the guide pipe has one end in a known manner such as a movable cover. Two fixed spiral cables or pitched cables 22; 24 are guided. The roof frame member 10 further includes a bearing cover 26 (not shown in FIG. 1). As shown in FIG. 5, the driven pinion 12 is driven by the worm gear of the worm transmission 28 in a known manner. In this case, the worm gear meshes with the worm shaft provided at the front end of the shaft of the drive motor 30, and therefore the rotation of the driven pinion 12 is strongly decelerated with respect to the rotation of the motor shaft.
[0010]
The rotation axes or support axes of the gears 14 and 16 and the pinion 12 are arranged on one straight line. In this case, the gears 14 and 16 and the pinion 12 are provided between the two guide pipes 18 and 20, that is, between the drive cables 22 and 24. The guide pipes 18, 20 are provided with openings 32, and the gears 14, 16 engage with the drive cables 22, 24 via the openings, respectively, in which case each gear 14, 16 is strictly Engage with each cable 22, 24 at one location. The driven pinion 12 is provided on the same dentition surface as the gears 14, 16 and meshes with both gears 14, 16. Therefore, the rotation of the driven pinion 12 in one direction is the reverse of the gears 14, 16. Inducing the rotation at the same speed in the direction, the gear also introduces the torque transmitted from the driven pinion 12 into the drive cables 22 and 24 as a drive force, and thus the drive cable is driven in the opposite direction, in this case The introduction of force into each of the two drive cables takes place in two places: the engagement point of the gear 14 and the engagement point of the gear 16. Thus, for a given torque of the driven pinion 12, the load at each force introduction point on the drive cables 22, 24 is thus essentially an essence compared to the prior art where the torque of the driven pinion acts directly on the drive cable. Is reduced to 1/2. In the case of the present invention, the driven pinion 12 does not engage with the drive cables 22, 24. The diameter or the number of teeth of the driven pinion 12 is smaller than that of the gears 14 and 16, and therefore, deceleration is performed as compared to the direct force introduction from the driven pinion to the drive cable. The number of teeth of the gears 14, 16 may be slightly different, in which case the positions of the guide pipes 18, 20 and the drive cables 22, 24 are not exactly parallel. For example, the following number of teeth can be selected for gear 14, pinion 12 and gear 16: 22/16/25 and 23/15/26. Theoretically, the same number of teeth is possible.
[0011]
The essential advantages of the embodiment of FIGS. 1-5 in which the gears 14, 16 driven by the driven pinion 12 directly engage the drive cables 22, 24 are that the required number of components and the required structural space in the height direction are small. It is in that there is. However, since the teeth of the gears 14 and 16 must be suitable for engagement with the teeth of the pitch faced cables 22 and 24 and the driven pinion 12, the selection of the type of dentition is not free. That is, for example, an extended line dentition is impossible.
The embodiment shown in FIGS. 6-8 differs substantially from the direct engagement embodiment described above in the following respects. That is, both gears 115, 117 engaging the drive cables 22, 24 are not driven directly, i.e. not driven by the driven pinion 12 in the same dentition plane. Supplementary gears (primary gears, primary gears) that are directly engaged with the driven pinion 12 and are installed so as not to be idled coaxially with respect to the gears (secondary gears, secondary gears) 115 and 117 to drive the gears (secondary gears, secondary gears). 114 and 116 are provided. For this reason, a common shaft 140 is provided in which the gears 114 and 115 and the gears 116 and 117 are installed so as not to idle. If the number of teeth of the primary gears 114 and 116 engaged with the driven pinion 12 is selected to be larger than the number of teeth of the corresponding secondary gears 115 and 117, the rotation of the driven pinion 12 can be supplementarily reduced. A further essential advantage of this embodiment is that the teeth of the secondary gears 115, 117 engaging the drive cables 22, 24 and the teeth of the primary gears 114, 116 engaging the driven pinion 12 are different. That is, it can be optimized with respect to the engagement purpose concerned. In this case, in particular, an extended line dentition is also possible. The disadvantage of this embodiment over the previously described embodiment lies in the larger required structural space in the height direction and the use of supplemental components (two supplementary gears).
[0012]
In summary, the present invention is a prior art that provides only one force introduction point per cable by providing at least two force introduction points for each cable to transmit a given torque of the driven pinion to the drive cable.
